BICYCLE-SADDLE.

SPECIFICATION formingpart of Letters Patent No. 613,295, dated. November1, 1899. Application filed August 23, 1897. Serlal No. 649,123- (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, BRADFORD MOGREGOR, a citizen of the United States,and a resident of Covington, Kenton county, State of Kentucky, haveinvented a certain new and useful Bicycle-Saddle; and I do declare thefollowing to be a clear, full, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, attention being called to the accompanyingdrawings, with the reference-numerals marked thereon, which form a partof this specification.

This invention relates to improvements in bicycle-saddles, andparticularly to the construction and shape of the seat and the manner ofits support. The seat is improved to conform to hygienic and anatomicalrequirements as well as to comfort, and the support is of a kind tofurnish a yielding adjustment at all points in any direction, thuspreventing more effectually the transmission of jars and jolts to therider.

In the following specification and particularly pointed out in the claimis found a full description of the invention, its manner of use, parts,and construction, which latter is also illustrated in the accompanyingdrawings, in which- Figure 1 shows in elevation a part of a bicycle withmy improved saddle in position. Fig. 2 is a top viewof the seatenlarged. Fig. 3 is a top View of the springs supporting the same. Fig.4 is anenlarged side View of the saddle. Fig. 5 is a verticalcross-section of the same. Fig. 6 is a longitudinal section showingshape of the seat.

8 is the seat, which I construct of sheet metal finished so as to obtaina smooth and polished as welLas rigid and unyielding surface. Aluminiumor plated metal is suggested, with preference for the former. Forventilation a central slot 9 with perforations 10 to either side areprovided. The top surface of the seat inside of the outerdownwardly-turned edge is slightly depressed toward the center, withportions 11 11 to either side of the central line or slot 9, concavedstill deeper to receive the large posterior hip muscles, (glutwusmaximus.) The front edge of the seat is practically straight without theusual horn-shaped projection, having in place an indentation 12, therebyavoiding soreness and irritation.

The seat is supported on springs only, there being at no point a rigidconnection, as is the case now in most saddles. These spring-supportsare distributed around below the outer edge of the seat and across belowthe straight front of the latter, and consist, preferably, of a nest ofspiral springs 13, with their upper ends connected to the under side ofthe seat. This connection may be in any suitable manneras, for instance,by solder or riveting. The lower ends of these springs rest on brackets14, one for each spring, and projecting from a supporting-center in formof a hub 15, which is horizontally perforated to receive the usualseat-support 16 of the saddle-post of the bicycle-frame. A set-screw 17serves to hold it in place. In practice these brackets are formed byextending the Wires 18 at the lower end of each of the springs inwardlyand connecting them by solder, riveting, or screw-thread to thesupporting-center, near one end thereof. An additional wire 19,connected to the center in a similar manner, is then twisted about wire18 near its outer end, below the spring, thus forming a rigid andsubstantial triangular trussbracket which prevents transmission of anystrain caused by the movement of the springs to the point of connectionat hub 15.

As will be seen, this saddle is very convenient and comfortable, and theseat being shaped to conform to the parts with which it comes in contactprevents irritation and soreness. While the seat itself is rigid andunyielding, its manner of support permits it to yield at any point andin any direction, vertically as well as laterally. The material selectedprevents the absorption of moisture and perspiration.

Having described my invention, I claim as new- In a bicycle-saddle, thecombination of a metal seat, spiral springs secured to the under sideand around the outer edge thereof, supporting-brackets one for each ofthese springs and a supporting-center 15 to which these brackets areconnected, each of these latter being formed by extending at the lowerend of each spring, the wire 18 of which they In testimony whereof Ihereunto affix my are composed inwardly, and by an additional signaturein presence of two witnesses. wire 19 connected to each of wires 18below the corresponding spring above and also ex- 5 tended inwardly, theends of both of these Witnesses:
